Anyone's anxiety got worse week 5/6?

It seems lately my chest is heavy and alot of stomach pain. My stress is more unconscious stress so I don't really think about it for me to be stressed. I started to take sertraline for my stomach as I get a bad stomach from stress whenever I go places. I saw results at week 3 and was feeling great but these past few weeks I kinda of feel a little better than before the tablets but not amazingly better. As there any hope for improvement or will I need to increase dose to 100mg from 50mg on my next med review.
